SBC v2 uses a 2-lead bi-color LED at D1 (per schematic). Red/Green
is suggested.
Depending upon your drivers (LS or HCT), you may wish to reduce the
value of R9 from 100 ohms to 47 ohms to increase brightness. I
wasn't satisfied with the LED brightness until I reduced R9 to 22
ohms -- but I am using LS logic throughout the board. Keep the 100
ohm value to start if you are using HC or HCT logic.

So, I'm still a bit confused... Is it a single or bi
color LED? Parts list specifies a single color one but you are all
saying it is red/green?

Or
just connect the LED to a 5V through 470 ohm resistor, and check
the polarity and the colors :-)
